Tropical Storm Fiona approaches Puerto Rico: Latest forecast

Heavy rain is expected and flash flooding and mudslides are possible.

Tropical Storm Fiona is taking aim on the Caribbean and is set to bring heavy rain and possible flash flooding and mudslides to Puerto Rico this weekend.

Puerto Rico will see the first impacts from Fiona early Saturday morning. By Saturday afternoon and evening, the heavy rain will move in as the core of the storm churns just south of the island.

The heavy rain will continue into Sunday morning with the threat of flash flooding and mudslides lingering.

Most of the island could see 3 to 6 inches of rain, but the mountains could see 6 to 10 inches.

Fiona's winds are expected to approach 65 mph, which is considered a strong tropical storm (a category 1 hurricane begins at 74 mph).

Widespread power outages are possible across Puerto Rico.
